To all whom it may concern:

Philadelphia, in the county of Philadelphia and State of Pennsylvania,have invented certain new and useful Improvements in Bosom-Presses,whereof the following is a specification, reference being had to theaccated at a convenient point to be manipucompanying drawings.

My invention relates to a laundry machine I commonly known .as a shirtbosom press,

which is pneumatically operated. In machines of this type, there areemployed a I plurality of movable members withpadded surfaces upon whichthe goods are placed and which are forced 1n succession agalnst a heatedstationary member, whereby pressure is exerted to secure the requiredfinish. I

By my invention I secure an easy and uniform control and operation ofsuch a machine by'means of'the application of pneumatic power. air fromthe pneumatic cylinder for the purpose of drying the padded heads of themovable member and thereby greatly economize in the power necessary tooperate these machines, and also simplify their construction and reducetheir cost.

.In the accompanying drawings, Figure I, is an elevation of a shirtbosom press conveniently illustrating the application of my inventionthereto. Fig. II, is a cross sectional view of the padded head employedin the press.

The device consists of a bed frame or base 1, which supports near itsends apair of posts 2, and 3, whose tops are reduced to form shoulderswhich are bridged by a yoke 5, secured in place by nuts 6. The yoke 5,supports ahollow steam chest or headlO, constituting the fixed member ofthe press, and having a circular opening 11, in which is received theneck band of theshirt. The lower face of this head is highly polishedand maintained at the required temperature by means of a steam pipe 12,which extends from some suitable source of steam supply, andcommunicates with its hollow interior.

Pivotally mounted on the post 2, is a swinging turntable 15, having thelaterally The said heads are arranged to be alter-- nately swung underthe stationary steam I further employ the exhaust chest 10, againstwhich either one so swung is forced by means of the piston rod 25, ofthe pneumatic cylinder 26, which is bolted or otherwise secured to thebed 1. The operation of the piston 27, of the said cylinder is under thecontrol of a slide vvalve 28, incased within a valve chest 29, which islated by the feet of the operator by means of a double foot lever 30,which is pivoted at 31,-to a lug formed on the top of said chest. Thefoot lever 30, comprises the arms 32, and 33, to the latter of which ispivot-ally attached a rod '35, which slides through a stuffing box atthe top of the chest and is secured at its lower end to the valve 28;The said valve is maintained in airtight contact with the inner face of,the wall 36, of the chest 29, by means of a spring 37, which is inengagement with the back there of, and maintains it in whatever positionit is placed by the foot lever 30. The said chest is in communicationwith a source of plied and exhausted through a pipe 45,

which extends from its bottom" to the right side of the valve chest 29,and is arranged to exhaust through the recess 46, in the slide valve 28,into a pipe 50, which also extends from the right side of the valvechest in close proximity to the pipe 45. The exhaust pipe 50,communicates witha duct 51, which communicates with branch ducts 52, and53, extending respectively through the arms 16, and 17, of the turntable15. These lead to vertical ducts 55, in. the stems 20, which terminatein the chambers 56, of the heads 21. As best seen in Fig. II, the topsof said heads are provided with a plurality of apertures 57, throughwhich the exhaust air finally escapes. The heads are covered with pads58, of felt or other suitable material secured by means of a textilefabric 59. During the process of pressure ironing, this pad absorbs themoisture previously applied to the shirt bosom, and the air whichexhauststhrough the apertures 57, is per-' mitted to pass through thepad and thus eliminates this moisture upon the completion of the ironingof each shirt.

The operation of the device is as follows :The dampened shirt bosom isstretched across the top of one of the heads 21, in a well known mannerand the turn- H table 15, is thereupon swung, so that its piston causesthe stem 20, to be elevated thus forcing the head 21, against thestationary steam chest 10. The shirt bosom is thus permitted to remainunder pressure for a proper interval of time against the heated head.After this period has elapsed, the arm 33, of th foot lever is depressedand the valve 28, is thereby shifted to the position shown in thedrawing. The Weight of the piston 27, and the acting stem 20, causes theentrapped air to be forced from the cylinder 26, into the pipe 45,wherefrom it escapes through the recess 46, of valve 28, into the pipe50,,and through ducts 51, 52, 53, and 55, into the chambers 56, in theheads 21, where it finally asses out through the apertures 57, andpadding 58, in a manner and for a purpose hereinbefore explained.

Having thus described my invention, 1 claim I In a bosom press, thecombination of uprights and a yoke supporting a heated stationarymember; a plurality of padded movable members mounted each upon a stemseated in an arm swinging upon one of said uprights; a pneumaticcylinder having a piston rod capable of engagement with the stem ofwhichever movable member is in posit-ion to cooperate with thestationary member; a pneumatic valve by means of which compressed air isadmitted into said pneumatic cylinder to operate it; and ducts passingthrough said upright and swinging arms, the pneumatic valve chambercommunicatin with one of said ducts, whereb the air ex austed from thepneumatic cy inder is caused to ass through the padded heads of saidmova le members.

In testimony whereof, I have hereu to signed m name, at Philadelphia,Pennsylvania,'th1s thirteenth da of Janua 1911.
